22 maj 2023 · Papillary muscle rupture is a rare and potentially fatal complication that typically follows a myocardial infarction or occurs secondary to infective endocarditis. Acute rupture frequently results in severe mitral valve regurgitation, acute life-threatening cardiogenic shock, and pulmonary edema.
7 maj 2013 · Here, we detail a case of an elderly woman with acute mitral regurgitation caused by a spontaneous rupture of a papillary muscle. This rupture was likely related to severe mitral annular calcification with myocardial and valvular extension.
22 maj 2023 · Papillary muscle rupture is a rare and potentially fatal complication often following a myocardial infarction or secondary to infective endocarditis. Acute rupture frequently results in severe mitral valve regurgitation and subsequent acute life-threatening cardiogenic shock and pulmonary edema.
A 52-year-old man presented with acute onset of chest pain and was found to have an inferolateral ST-segment elevation myocardial infarction and acute mitral regurgitation due to papillary muscle rupture.
6 mar 2023 · Spontaneous, non-ischemic papillary muscle rupture (PMR) is a rare and life-threatening cardiac emergency. As a rare form of acute heart failure and hemodynamic compromise, urgent evaluation and diagnosis is needed as PMR is often fatal unless emergent repair or valve replacement is instituted.
Mechanical complications of acute myocardial infarction include papillary muscle rupture with severe mitral regurgitation, ventricular septal rupture with acute ventricular septal defect, acute and subacute free-wall rupture, and hemodynamically significant right ventricular infarction.
15 lis 2010 · Rupture of papillary muscle is a rare but catastrophic mechanical complication after myocardial infarction (MI). 1 It is well recognized that the posterior papillary muscle is involved in ruptures more frequently than the anterior papillary muscle. 2 The vulnerability of the posterior papillary muscle is considered to be caused by its usual ...
